My toilet is experiencing phantom flushes. What should I do?

Sometimes, you may hear your toilet refilling as if a person has flushed it. If your toilet cuts on and off without any person flushing it, this is called a Phantom flush. The reason behind this is a very slow leak from the tank into the bowl. Typically, the problem is caused by a worn-out flapper or flapper seat.

To correct the problem, you will have to drain both the tank and bowl, monitor and clean the flapper seat, and change the flapper if it’s worn out or damaged.

How does the revolution 360 degrees swirl flushing technology work?

This is one of the most potent flushing mechanisms from Kohler. This technology works in a similar way to the Aquapiston flushing system. Water leaves the flush canister via a single powerful force that ensures the entire bowl is covered to provide an efficient flush. So, it rinses the bowl effectively and leaves the toilet looking clean.

How to solve Kohler Santa Rosa’s toilet flushing problem?

The Kohler Santa Rosa toilet comes with an efficient gravity flushing system. When you press the flush button or lever, the flapper on the toilet rises and empties the entire water in the tank into the bowl. But if the toilet stops flushing, you must check the trip lever or flush valve. The chain connection might loosen. So fix the chain to avoid excessive slack.

But if your toilet flushes but doesn’t have enough power, then something may block the flushing system. So you need to check if there is any blockage in the Tet, Trapway, or bowl rim holes. Clear the blockage and adjust the water level in the tank.
